Large adjustable speed drives designed to raise your profitability You would surprised how many industrial processes can improved using adjust­ able speed electric motors. The energy savings alone drive few megawatts can offset the cost the speed control system just months few years. Maintenance • Less stress and wear reduces the maintenance requirement. • Mean time repair typically hour Emissions • Electric drives avoid emissions. • Substantial energy savings Reliability • Mechanical flow control devices as potential source failures are eliminated. • «Softer» control reduces wear motor and driven plant. The larger the process and the higher the performance demands, the greater the benefits from electronic speed control. Processes and industries - power plants - chemicals and petrochemicals - building materials - metals - mining - research and development - water and sewage treatment - marine and offshore - oil and gas - pulp and paper Reasons for using MEGADRIVE-LCI Efficiency • Compressors, fans and pumps run at their optimum operating point. (a significant advantage today's world) • Noise reduced the minimum possible. Better process control • greater accuracy • smooth control low flow rates • wider range control • faster response with greater stability • reduced production waste and higher quality • set-points quickly reached and therefore shorter production times • renowned reliability and adaptability Soft starting • less mechanical stress motor and driven plant • minimum repercussions the supply system • reduced temperature rise while the motor is accelerating • need pony motors and clutches • starting very large motors and generators Typical applications Speed control and soft starting of - fans and pumps - high-speed compressors - reciprocating compressors - wind tunnel blowers - blast furnace blowers - rolling mills - extruders - marine propulsion systems - test bays Substantial savings energy and maintenance costs Smoother running results in - higher productivity - longer plant life 2
